Patented June 30, 1936 UNITED STATES PATENT OFFICE MANUAL AND RECORD CONTROLLED MACHINE Application February 27, 1935, Serial No. 8,445

70 Claims.

This invention relates to accounting machines in general.

The broad object of the invention is to provide a machine for punching data in accounting and statistical records such as those used in the weil known Hollerith and Powers accounting machines.

An object is to provide a machine for printing data on accounting and statistical records.

Another object is to provide a machine designed to automatically duplicate either all or only selected portions of the data on a master record as by punching and/or printing such data in another record.

A further object is to provide a combined record punching and printing machine which can be operated completely automatically without intervention by the operator.

Still another object is to provide a novel power drive mechanism for the punching and/or printing mechanisms of accounting machines, typewrit-ing machines, punching machines, and the like. 7

An object is to provide a positively engaging power drive mechanism for punches and/or type bars which is designed to prevent mis-operations or incomplete operations of punches .and/or typebars.

Another object is to provide a combined typewriting and punching machine which may be completely electrically controlled.

f A further object is to provide an improved automatic column skipping mechanism or tabulating mechanism.

Another object is to provide a novel record ejecting mechanism which is controlled automatically by movement of the carriage which feeds the records while they are being punched and/or printed.

Other broad objects are to generally improve record perforating and printing machines by making them simpler, more positive in operation,

and less likely to get out of order, and by making them easier to operate.

Other objects will be pointed out specifically in the following description and claims or will be apparent from a study of the description, claims and drawings.

In the drawings:

Fig. 1 is a front elevation of the machine.

Fig. 2 is a top plan view.

Fig. 3 is a vertical section on the line 33 in Fig. 1.

Fig. 4 is a vertical section on the line 4-4 in Fig. 1.

Fi 5 is a vertical section on the line 5! in Fig. 1.

Fig. 6 is a partial vertical section, showing the card carriage, card guides, and card feeding roller mechanism.

Fig. 7 is a vertical section showing the keys, type bar operating mechanism, and punch operating connections in normal position.

Fig. 21 is an enlarged right side elevation of one of the card engaging fingers.

Fig. 22 is an enlarged front elevation of the mechanism for operating the last column contacts.

Fig. 23 is an enlarged front elevation of the contacts controlled by the column stops with the protecting cover shown in section.

Fig. 24 is a vertical section on the line 24- in Fig. 6 on a larger scale than Fig. 6.

Fig. 25 is a fragment of a specimen card.

Fig. 26 is a fragment of a card punched and printed to illustrate the combination hole code.

Fig. 27 is an enlarged plan view of the duplicator table.

Fig. 28 is a vertical section on line 28-28 in Fig. 2'7.

Fig. 29 is a detail view of certain parts shown by dotted lines in Fig. 27.
